_clean_sub_graphs() is indeed a function within apls.py, so I'm not sure of the source of this error. Try the updated version of apls to see if this is resolved.

Hi @avanetten,
I tried the latest version of apls when it has this error. I think the problem related to the underscore _clean_sub_graphs(). And python3 cannot import the underscore function. I changed the function to without underscore, then it works fine for me.
